The only issue with the L&M is that battery--and it depends on which side of the fence you're on.

The integrated battery is nice, compact and neat. There are no wires hanging about or battery packs velcroed to the bike.

On the downside, you can never have a spare battery pack. When the built-in cells go bad, you throw the whole thing out. And it's another proprietary charger kicking around the house,that's good for nothing else.

It's for this reason I went with the DiNotte, $150 at Geoman Gear. It takes generic rechargeable AAs and uses a generic recharger. I can charge and carry as many spares as I like. When one goes bad--which has happened--I replace only the battery and still have the light, charger, etc.
